The Omron VB-3241 is a durable multiple limit switch equipped with three roller plungers for accurate multi-point detection. Each plunger uses a 6.8 mm diameter roller and operates with consistent response at speeds between 0.1 mm/s and 0.5 m/s. This model features side cable entries and a no-flange structure, allowing compact and flexible mounting in equipment with tight space constraints.
With a 10 A contact rating at 250 VAC, the switch handles resistive loads reliably across 300,000 electrical cycles and 5 million mechanical operations. Built to withstand harsh industrial conditions, it offers IP67 protection against water and dust, 100 MΩ insulation resistance, and low 15 mΩ contact resistance. It also meets strict vibration (10–55 Hz) and shock (1,000 m/s² destruction) standards.
The VB-3241 is suited for conveyors, indexing machinery, and control systems requiring compact, reliable multi-plunger switching in harsh environments.
